This sculpture of The Greatest was made with 1,300 punching bags. Each speed bag was treated as a pixel and when put all together, formed the face, and classic snarl, of Muhammad Ali. The rest of the 22-foot high installation uses 6.5 miles of stainless steel cable, 2,500 pounds of aluminum piping and took three years to complete.

It was made by Michael Kalish and will be on view at Nokia Plaza in LA Live in March. [Wired]

You can only see Ali's face from one vantage point. Other perspectives show a bunch of steel and punching bags.
